摘要：Disclosed are “black-box leases” that protect information consistency andthat allow for information sharing in a distributed file system while hiding from a client
information about other clients' use of the file system. This information hiding also allowsgreater concurrency because changes to the file system are permitted as long as they donot affect the leases as observed by the clients. For each data field protected by a black-box lease, a client has a two-value data structure: SelfValue represents the client'sintended use of the data field, and OtherValue is an aggregation of the other clients'intended uses of that data field. Knowing only this aggregate OtherValue, but withoutknowing any specifics of the other clients' usage patterns, the client knows how it mayuse the data field without adversely affecting the consistency of data in the distributedfile system.
